LOL You're probably right in that being pregnant doesn't help much.
Remember that forgiveness is a DECISION - which means that it is NOT an emotion. Forgiving is something we decide to do because it's the right thing and we are commanded to do so; it's not something we have to "feel like doing" before it can be done.
Continuing to give it to God every time it comes to mind is exactly what that is about. Forgiving is a process, starting with the decision to do so, and then letting God work it out of your heart. You're doing exactly the right thing!
What does the Word say about forgiveness? How many times are we supposed to forgive? "I tell you, not seven times, but seventy times seven." Right? Forgiveness doesn't depend on the other person's action or repentance. It's our own heart attitude and deciding not to hold their actions against them - loving the sinner, even if we hate the sin.
Keep doing what you're doing and seeking the Lord over this! He will change your heart!
